Phase 1 - New RPC commands (no new deps): - getblockheader: header data from memory, zero disk reads - estimatefee: static fee estimation (Bitcoin Core compatible) - getblockchaininfo: chain state, difficulty, moneysupply - getwalletinfo: balance, stake, txcount, keypool, encryption - getnetworkinfo: version, protocol, connections, proxy - gettxoutsetinfo: height, bestblock, total_amount Phase 2 - REST API layer (-rest=1): - /rest/chaininfo.json, /rest/block/<hash>.json|hex - /rest/blockheader/<hash>.json, /rest/tx/<txid>.json|hex - /rest/blockhashbyheight/<n>, /rest/mempool.json - CORS headers for browser-based explorer access Phase 3 - ZMQ pub/sub notifications (optional, USE_ZMQ=1): - Topics: hashblock, hashtx, rawblock, rawtx - Conditional compilation via ENABLE_ZMQ Phase 4 - SSE real-time notifications (-ssenotify=1): - GET /events endpoint (authenticated, long-lived) - Block and transaction event streaming - 15-second keepalive for proxy compatibility Phase 5 - Address index (-addressindex=1): - getaddressbalance, getaddressutxos, getaddresstxids - LevelDB-backed index updated in ConnectBlock/DisconnectBlock - Requires -reindex on first use Also fixes QDesktopServices missing include for Qt5.
